Table 2. F-values from ANOVA testing the effect of region, foraging strategy and their interaction (df = 2,2,4) on morphological features of ants.

source	Weber’s L	femur L	pronotum W	eye position
foraging strategy	21.67***	4.46*	7.07***	0.88
region	769.88***	27.81***	60.38***	135.80***
region*foraging strategy	2.72*	1.72	0.63	9.85***

All measures except Weber’s length are based on residuals with Weber’s length. L = length; W = width. Values shown are F values. Results for post-hoc t-tests are shown in Fig. 1. Significance levels:

^*P<0.05,

^**P<0.01,

^***P<0.001.
